Kamelin (2005) who named these as alpine grass carpets (Kryonanocoryphion eurasiaticum), noted that this type of vegetation is characteristic of the Altai-Sayan mountain region, where alpine carpets are the highest floristic diversity in Asia.\u0000\u0000The snow-bed communities occupy macro- and megachionic ecotops (Kholod, 1993) in sites with excessive accumulation of snow in winter, which is preserved in the summer in the form of snow-beds. Usually snow-bed communities cover patches from several tens to several hundred square meters. The habitats of these communities are characterized by: 1) short ve­getation period due to the long period of the thick snow cover (up to 5 m) melting; 2) cold moistening during the most part of growing season because the melting of snow, and the inflow of water from nearby or underground springs; 3) no genesis of bog soils (Sedelnikov, 2017).\u0000\u0000Earlier syntaxa of the class Salicetea herbaceae were considered as a part of the alliance Salicion tur­czaninowii Ishbirdin in Ishbirdin et al. 1996, the order Salicetalia herbaceae Br.-Bl. in Br.-Bl. et Jenny 1926.\u0000\u0000105 relevés were sampled in 1998–2015 (Fig. 1), also we used 28 relevés published earlier (Chytrý, et al., 1995; Danihelka, Chytrý, 1995; Korolyuk, 2001; Telyatnikov et Mamakhatova, 2011; Ermakov, Zibzeev, 2012; Telyatnikov, 2013).\u0000\u0000An analysis of the coenoflora of the alpine-subnival snow-bed communities revealed the dominance of high-altitude species with a South Siberian and ­Central Asian areal (Aquilegia glandulosa, Carex altaica, Dracocephalum grandiflorum, Festuca kryloviana, Gentiana grandiflora, Hedysarum austrosibiricum, Luzula sibirica, Solidago dahurica, Tripleurospermum ambiguum, Veronica densiflora, Viola altaica). High constancy and often domination by shrubs of the genus Salix (Salix berberifolia, S. rectijulis и S. turczaninowii) are common for these communities. The originality of species composition of the chionophilic meadows of the North Mongolia and East Kazakhstan allowed to suggest the new order Sibbaldio procumbentis–Ranunculetalia altaici ord. nov. hoc loco and two alliances: Ranunculion altaici all. nov. hoc loco and Salicion turczaninowii Ishbirdin in Ishbirdin et al. 1996.\u0000\u0000The snow-bed communities are included in five associations (three ones are new), two subassociations, and two variants.\u0000\u0000The order Sibbaldio procumbentis–Ranunculetalia altaici ord. nov. hoc loco (Table 2) includes the snow-bed communities of South Siberia, North Mongolia and East of Kazakhstan.

Lawns are the most common element of urban landscapes which, as a rule, occupy 60–80 % of the total green area of cities.

The Ufa city (54°44′00″ N and 55°58′00″ E) is situated on the banks of the Belaya River, at the Ufa and Dema ri­vers confluence, on the Pribelskaya hilly plain, 100 km west of the Southern Ural ranges within the northern part of forest-steppe zone.

All species are included in the «black list» of the Republic of Bashkortostan (Abramova, Golovanov, 2016a), and the «Black book of the flora of Central Russia» (Vinogradova et al., 2010). The studies was conducted in the period 2016–2018 on the republic territory. The wide distribution of species and their naturalization in the meadow and semi-natural communities of the Southern Urals are noted (Abramova, 2011, 2014; Abramova et al., 2016; Abramova, Golovanov, 2018). In the centers of invasion of the studied species, 83 geobotanical relevés of communities were performed on sample areas of 10–100 mІ. Location, date, area of the described area, total cover, mean and maximum height of grass layer were indicated for each sample plot. The classification of communities involving these invasive species was carried according to Braun-Blanquet method with Kopecký–Hejný approach (Kopecký, Hejný, 1974). The identified syntaxa were compared with the units previously described in the studied area and other regions. Ecological regimes of communities are determined using the weighted average of the Landolt’s optimum ecological scales by IBIS 6.2 software (Zverev, 2007). The weighted average values are calculated according to the following scales: moisture (F), acidity (R), soil richness with mineral nutrients (N), humus content (H), light (L) and continentality (K). The Detrended correspondence analysis (DCA-ordination) method was applied using the CANOCO 4.5 software package to identify the patterns of ecological differentiation of invasive communities. Herbaceous perennials plants Solidago canadensis and S. gigantea left the decorative culture and now are naturalized in meadows along roadsides, forest edges, wastelands, fallow lands, around gardens near large cities. The most common species is S. canadensis, common in the vicinity of human settlements. S. gigantea is first recorded only in 2017 in the North-West of the republic, where it formed monodominant communities on the territory of abandoned garden plots. The ass.

The participants were from 11 cities of Russia and 7 Republics of the Caucasus and represented 14 institutions. Proceedings of the conference were published by the beginning of the meeting the book of abstracts includes 49 papers on the study of vascular plants, bryophytes, lichens and fungi, plant communities, as well as the protection of rare and endangered species, unique plant communities, and ecological problems in the Caucasus. The following geobotanical topics were highlighted in 13 papers: forest communities (3 reports), meadow and steppe vegetation (2), xeric open forests (2), communities of ecotone areas (1), structure of populations of rare plant species (3), as well as the history and current status of nature protected areas (2). The great emphasis has been focused on the study of floristic composition and plant populations. Thus, the conference showed that very few studies от vegetation are currently carried out in the Caucasus, and a lot of districts are not affected by the research. The greatest attention is paid to forest vegetation while meadow, steppe, alpine heath and xerophytic communities are studied rather poorly. Besides, there are “white spots” — mire, floodplain and aquatic vegetation. In nowadays, when the anthropogenic impact on the plant cover of the Caucasus is intensively increasing, it is especially important to study natural undisturbed communities preserved in protected natural areas. Another important issue is the conservation of the unique vegetation cover of the whole Caucasus. Thus, the study of vegetation of this region opens a wide field for researchers using various methods of modern plant science.","PeriodicalId":37606,"journal":{"name":"Rastitel''nost'' Rossii","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45774323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dataset contains 756 relevés: 647 made by authors during the field seasons of 2002–2018, while 109 taken from published monography (Mirkin et al., 1985). The alliance Caucalidion combines weed communities on rich carbonate chernozem soils in the forest-steppe zone.
